High Precision and Lockable Manual Polarization Rotator/Controller

SKU: POCM

The Manual Mini Polarization Controller is based on a novel design featuring high precision, ultra-compact size, low loss, high extinction, and lockability. Unlike conventional fiber strain-based polarization controllers, the POCM contains three rotatable waveplates between a pair of collimators to provide all possible polarization states with high precision and repeatability. Rotation is accomplished by using a finger or a screwdriver and locking in position via a magnet. Once the polarization positions are selected, they can be locked in position without drift for years. The conventional strain-based polarization controller changes over time. It is designed for modules or systems with limited space.
